Reinforced concrete damage assessment via metal magnetic memory

Reinforced concrete structures are an essential part of modern infrastructure, and their safety and lifespan are critical. These structures are affected by load-induced and cyclic stresses over time, which can cause concealed structural damage and threaten their integrity. In general, the beam's integrity is determined by the reinforcement in the concrete. As an outcome, monitoring the behaviour of the reinforcement in the concrete is crucial to ensuring the reinforced concrete beam's integrity. The main purpose of this research is to examine the behaviour of the reinforcement in the beam under cyclic loading utilizing a magnetic metal memory (MMM). 8 reinforced concrete beams measuring 150mm x 200mm x 1750mm were produced and subjected to cyclic loading using three point loads. Throughout the fatigue test, the maximum load and minimum load of 90% and 20% of the beam's ultimate load were applied. The MMM was used to scan the underneath of the beam at the centre in a distance of1150 mm. Visual observation was employed in observing the crack that developed in the beam surface under cyclic loading. The MMM approach was discovered to be useful in the detection of RC beam damage. It has the potential greatly improve RC beam safety. Early and accurate damage assessment identifies and mitigates structural faults, lowering the danger of unexpected failure and assuring occupant and public safety.
